“…Therefore, the input signal tilted 45°of the polarizer divided vertical and horizontal polarization and two signals passing through polarizer have approximately 0 dB difference in magnitude, 90°difference in phase between two signals. In this article, the designed polarizer have LHCP in Tx band and RHCP in Rx band and the axial ratio is less than 1.0 dB in Tx‐band and 1.5 dB in Rx‐band and VSWR is less than 2.0:1.…”

“…The circularly symmetric radiation patterns arise from the use of TE 11 and TM 10 , HE 11 modes. The corrugated horn antenna is consisted of a circular input waveguide, which dominant mode is TE 11 mode, a slant taper for TM 10 and the inside wall that have slots and teeth for hybrid mode. The HE 11 generated by a combination of these different modes make a uniform signal distribution on a aperture of the corrugated horn and implemented above described performance [9].…”

Antenna and RF system for fly‐away satellite terminal communication applications on ka‐band is presented in this article. Fly‐away satellite terminals 1 or 2 people is fixed by installing motion terminal, movement and installation of equipment, and ease of operation to the user's for low‐power consumption, small size, and light weight is important. For low‐power consumption and compact and light‐weight, dual‐reflector antenna system volume using dual‐offset Gregorian antenna structure is minimized, magnesium by weight is minimized. Transmitter part of RF systems has low‐power consumption and compact light weight using the pHEMT MMIC compound devices. For harmonic rejection, the photonic band‐gap low‐pass‐filter is designed. In receiver part, low‐noise amplifier and down converter rolled into one function of the low‐noise block converter structure is designed for compact and light weight. In this article, fly‐away satellite terminal with low‐power consumption and compact light weight is described by antenna system and RF system performances. © 2016 Wiley Periodicals, Inc.

The structure that transforms a linear polarized signal into right-hand or left-hand circularly polarized signals is called a polarizer. In this study, a dual-band waveguide polarizer used in satellite communications is presented. The waveguide polarizer is designed using iris structures on a square waveguide. The purpose of the polarizer is to transmit the ±45° tilted linearly polarized signal at its input to the output as a right-hand or left-hand circularly polarized wave, and vice versa. At the input of the polarizer, a transition is designed between the WR42 waveguide and the square waveguide. At the output stage, a transition from square waveguide to circular waveguide is designed. In this paper, the design steps of both the polarizer and the transition sections, the optimization parameters, and simulation results are presented in full detail. The simulations are performed with a commercial electromagnetic simulation software, CST Studio Suite. The design operates within the Ka-band, specifically at 17.2 – 21.2 GHz and 27.5 – 31 GHz frequency bands. The insertion loss of the iris polarizer is 23 dB, and the phase difference is less than 15° around 90° for both bands.

“…Moreover, recently multi‐band antenna feeds for satellite communication are used as the number of frequency bands increases [4, 5]. Iris polariser has such desirable properties as wide or multi‐band operation, compactness and simple interfacing requirements [6, 7].…”
